i can say that i did not know an average everyday camera is modded EXACTLY how the human eye is, because i got 20/20 vision, how many other people have that?
Everyone. If they don't, they use special corrective len's called glasses.
Just for the record, that's not exactly true. Glasses, and even combinations of glasses and contact lenses, cannot always correct a person's vision to 20/20. When a person's vision cannot be corrected to at least a certain point (20/200 maybe? Not at all sure on that) they are considered blind.
I have to admit, though, that I've never found orbs particularly impressive. Lee77, however, brought up an interesting point.

There have been ghosts captured on film, not the ridiculous “ectoplasm” that is nothing but flare, but human- and animal-shaped apparitions. Some people believe this “proves” the camera is capable of photographing something invisible to the naked eye; it does not. Any photographer knows that when looking at photos later, there are often people, vehicles, smokestacks, etc. in photographs that were not observed at the time the photo was taken. This doesn’t mean these objects weren’t there; we just didn’t see them. The apparitions caught on film such as the monk-like figure in a British church, the figure of Lord Combermere sitting in his library, the “Staircase Ghost,”
Does anyone have any idea how long something has to be visible in order to register on the naked eye? Some ghost photographs are taken when people present see nothing. Sometimes people see something and take pictures that reveal nothing. Sometimes the images that are captured seem solid, sometimes transparent.
I've been wondering if "ghosts" such as these might sort of "strobe" in and out of existence. For the purpose of explaining my idea, I'm going to say these ghosts go through two phases, (+) when they are visible and (-) when they are not. If the rate of fluctuation between the (+) and (-) is fast enough, they might appear solid to the human eye, however their appearance and solidity on film would be dependant on how closely their (+) phase coincided with the time when the film was exposed. In addition, a "ghost" that only went through one or two (+) phases might show up on film that happened to be exposed at the right time without being noticed by the naked eye.
Does that make sense?
Also, the degree of solidity of ghosts on film might have more to do with how closely their (+) phase matched the camera's exposure than any intrinsic solidity of the ghost itself. In this theory, transparent ghosts would simply be underexposed.
This is of course, only a theory, but I think it's possible and, if it could be somehow validated, it might open other avenues for research.
